M24512E-FMN6T4 [STMicroelectronics]

The M24512E-F is a 512-Kbit I²C-compatible EEPROM (electrically erasable programmable memory) organized as 64 K x 8 bits. It can operate with a supply voltage from 1.6 V to 5.5 V with a clock frequency up to 1 MHz, over an ambient temperature range of -40 °C / +85 °C.

The device offers three 8-bit registers, namely: the device type identifier (DTI) register, the configurable device address (CDA) register, and the software write protection (SWP) register.

The device offers an additional 128-byte page, called the identification page. This page can be used to store sensitive application parameters which can be (later) permanently locked in read-only mode.

The M24512E-F is available in the standard 8-pin TSSOP8, SO8N, UFDFPN8, and unsawn wafer.

On demand, the EEPROM can be delivered with a preprogrammed and locked device address.
